351 | * Sub carrier DDA | |

353 | * I think this works as follows: | |
354 | * | |
355 | * subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096 | |
356 | * | |
357 | * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value | |
358 | * | |
359 | * So, | |
360 | * dda1_ideal = subcarrier/pixel * 4096 | |
361 | * dda1_inc = floor (dda1_ideal) | |
362 | * dda2 = dda1_ideal - dda1_inc | |
363 | * | |
364 | * then pick a ratio for dda2 that gives the closest approximation. If | |
365 | * you can't get close enough, you can play with dda3 as well. This | |
366 | * seems likely to happen when dda2 is small as the jumps would be larger | |
367 | * | |
368 | * To invert this, | |
369 | * | |
370 | * pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size) | |

1272 | * | | active | |
1273 | * | top margin | |
1274 | * remainder of tv vblank | |
1275 | * | |
1276 | * When the TV encoder is used the pipe wants to run faster | |
1277 | * than expected rate. During the active portion the TV | |
1278 | * encoder stalls the pipe every few lines to keep it in | |
1279 | * check. When the TV encoder reaches the bottom margin the | |
1280 | * pipe simply stops. Once we reach the TV vblank the pipe is | |
1281 | * no longer stalled and it runs at the max rate (apparently | |
1282 | * oversample clock on gen3, cdclk on gen4). Once the pipe | |
1283 | * reaches the pipe vtotal the pipe stops for the remainder | |
1284 | * of the TV vblank/top margin. The pipe starts up again when | |
1285 | * the TV encoder exits the top margin. | |
1286 | * | |
1287 | * To avoid huge hassles for vblank timestamping we scale | |
1288 | * the pipe timings as if the pipe always runs at the average | |
1289 | * rate it maintains during the active period. This also | |
1290 | * gives us a reasonable guesstimate as to the pixel rate. | |
1291 | * Due to the variation in the actual pipe speed the scanline | |
1292 | * counter will give us slightly erroneous results during the | |
1293 | * TV vblank/margins. But since vtotal was selected such that | |
1294 | * it matches the average rate of the pipe during the active | |
1295 | * portion the error shouldn't cause any serious grief to | |
1296 | * vblank timestamps. | |
1297 | * | |
1298 | * For posterity here is the empirically derived formula | |
1299 | * that gives us the maximum length of the pipe vblank | |
1300 | * we can use without causing display corruption. Following | |
1301 | * this would allow us to have a ticking scanline counter | |
1302 | * everywhere except during the bottom margin (there the | |
1303 | * pipe always stops). Ie. this would eliminate the second | |
1304 | * flat portion of the above graph. However this would also | |
1305 | * complicate vblank timestamping as the pipe vtotal would | |
1306 | * no longer match the average rate the pipe runs at during | |
1307 | * the active portion. Hence following this formula seems | |
1308 | * more trouble that it's worth. | |
